hello guysss i have come in to a little/big problem.. ive got an iphone 4and its jailbreaked, my iphone got unlocked from att so im trying to restore so it can be done, but since apple doesnt sign 5.1.1 its kind of hard ive already try everything i have found on the web and the farest i have come is to error 11 (now im stuck in error 1600 again because tinyumbrella isnt bypassing it anymore :S) i tried sitching the ipsw with the shsh blob but still nothing, also tried jailbreaking it with redsnow to 5.1.1 and nothing.. so if some one know the answer for this problem i would really apreciate it .. thank you in advance
